The philosopher Sun Tzu once said the knowledge of oneself is important in facing whatever challenges we have in life (in particular our enemies, who or whatever they may be).
This is sound advice that most people should follow.
But many of us go through life not knowing much about ourselves, even the part we see the most: our bodies.
There are things about our bodies that we have no idea are actually happening everyday.
And it's actually a wonderful thing to realize that our bodies are as complex as they are.
Here are a few things you may not have known about your body before.
These interesting facts are certain to nab you a new appreciation of your body and everything about it: -Your brain has a huge appetite: Your brain may only have two percent of your total body weight but it requires about 20% of oxygen and calories from your body just to keep it going.
The stocking up of resources in your brain is done by three huge cerebral arteries.
When these arteries become blocked, your brain starves and part of it stops working.
And this is known as a stroke.
-Laughing is really contagious: Don't you notice that when you laugh genuinely and heartily, the room just lights up with you? Every time someone laughs a social cue is expressed that makes others laugh too.
And each time someone laughs the region in your brain associated with the movement of the face is stimulated.
So laugh and spread the joy! These are only a few of the many things going on in your body that you may not know about.
But hey, these are only a fraction out of thousands!
